Yes, I know that it works with Creators Update (1703), April 2017,but what about Fall Creators Update? (1709), October 2017,
it was released this month, and Outlook Express does not work for me, here is the error screenshot:

Version 2.2. released 4 days ago and works on fall creators update.

In simple words, version 2.2 work on up to the latest windows 10 release

Yes, I did read the forum, I am a technical person, there is not a single message with someone talking about Fall Creators update (1709), just the Creators update (1703).
And that is irrelevant to me, because I know that Outlook Express works on 1703 without problems.

So here I am, asking if anything can be done for it to work on 1709?
I think that not many people have this update installed yet, that is why no one asked about it.

You can check your Windows 10 version here: Start > Settings > System > About. There is a line with "Version".
Just to make sure that you are really running 1709, and not the earlier 1703.
